A nurse is instructing a group of clients regarding nutrition. Which of the following is a good source of omega-3 fatty acids that the nurse should include in the teaching?
Fish
Leafy green vegetables
Dietary supplements
Corn oil
The Correct Answer is A
A. Fish, particularly fatty fish such as salmon, mackerel, and sardines, are excellent sources of omega-3 fatty acids, which are beneficial for heart health and reducing inflammation.
B. Leafy green vegetables contain some omega-3 fatty acids, but they are not considered a primary source compared to fish.
C. Dietary supplements can provide omega-3s, but they are not food sources and may not be necessary if individuals can obtain omega-3s from their diet.
D. Corn oil is primarily high in omega-6 fatty acids, which do not provide the same benefits as omega-3s and can lead to an imbalance if consumed in excess.

Correct Answer is D
Explanation
A. Kussmaul respirations are characterized by deep, rapid breathing typically associated with metabolic acidosis, not alternating periods of hyperventilation and apnea.
B. Apneustic respirations involve prolonged inspiration and shorter expiration phases, usually seen in brain injuries, but do not reflect alternating hyperventilation and apnea.
C. Stridor is a high-pitched wheezing sound indicative of upper airway obstruction, which does not describe the breathing pattern in this scenario.
D. Cheyne-Stokes respirations are defined by alternating periods of deep, rapid breathing (hyperventilation) followed by periods of no breathing (apnea), making this the correct choice for the client’s described pattern.
Correct Answer is D
Explanation
A. Proceeding to measure the oral temperature immediately after the client has consumed ice chips can lead to an inaccurate reading due to the cooling effect of the ice.
B. Documenting that the nurse was unable to measure the client's temperature is unnecessary; it is possible to obtain an accurate measurement after a suitable waiting period.
C. Providing a sip of warm water will not resolve the issue of the ice chips affecting the temperature reading, as the nurse should still wait a longer period for accuracy.
D. Waiting 30 minutes after the client has consumed ice chips is the best practice, as it allows sufficient time for the oral cavity to return to a baseline temperature for an accurate measurement.
